# CrazyStone DeepLearning vs 詰碁の森

The clearest difference is ratings volume: CrazyStone DeepLearning at 1K against 詰碁の森's 21. 詰碁の森's advantage is update cadence (every 3 weeks vs every 2 months) and review sentiment (82% vs 71%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. CrazyStone DeepLearning sells 1 in-app purchase, starting at $2.99 per month and 詰碁の森 sells 8 in-app purchases, starting at $4.49 per month. Whichever you choose, the download price is not the number that matters.

詰碁の森 holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: CrazyStone DeepLearning has 1K ratings behind it against 21, so its average is the more settled of the two. Written reviews point the same way: 71% of CrazyStone DeepLearning's written reviews are positive against 82% of 詰碁の森's.

CrazyStone DeepLearning ships an update every 2 months, 詰碁の森 every 3 weeks. Both last shipped on October 29, 2026.
